Concepts of 20th century physics—quantum mechanics, theory of relativity, doctrine of indeterminacy—have had a profound effect on historiography. They provided scientific metaphors of relativity and uncertainty for distrusting written history. Involvement of the observer with the observed—so prominent in physical science both at the level of the atom and that of outer space—has been extrapolated to history writing as a bias factor.
